Materials Data on RbVF3 by Materials Project

RbVF3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with eight equivalent VF6 octahedra. All Rb–F bond lengths are 3.02 Å. V2+ is bonded to six equivalent F1- atoms to form VF6 octahedra that share corners with six equivalent VF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All V–F bond lengths are 2.14 Å. F1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent V2+ atoms.

Materials Data on Rb2VF6 by Materials Project

Rb2VF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with four equivalent VF6 octahedra. All Rb–F bond lengths are 3.08 Å. V4+ is bonded to six equivalent F1- atoms to form VF6 octahedra that share faces with eight equivalent RbF12 cuboctahedra. All V–F bond lengths are 1.88 Å. F1- is bonded in a single-bond geometry to four equivalent Rb1+ and one V4+ atom.
